SEL-F-OILING WHEEL FOR MINE-CARS.

Specification of Letters Patent.

Patented Aug. 1, 1905.

Application vfiled January 5, 1905. Serial No. 239,782.

l To @ZZ whom, it muy con/cern:

Be it known that we, JOHN FRANCIS WEIS- BROD, residing at Allegheny, and JAMES D. p RHODES, residing at Sewiclrley, in the county of Allegheny and State of Pennsylvania, citizens of the United States, have invented a or channels, or, in other words, the Outlets* from the receptacle, being constructed and arranged in such manner that no lubricant can escape while the wheel is at rest or is rapidly revolving and 'can escape only when and as long as ythe wheel is turning at .slow speed in either direction.

In the accompanying drawings, illustrating the invention, in the several figures of which like parts are similarly designated', Figure 1 is a sectional perspective view of the self-oiling wheel for mine-cars, the near wall of the receptacle being broken away; and Fig. 2 is a front elevation. Fig. 3 is a perspective view of the lubricant-receptacle detached, with the two near sides removed; and Fig. L1 is a side elevation thereof, the end wall being broken away.

The wheel 1, with its hub 2, may be of'any approved construction, excepting that two of its adjacent spokes are connected front and bacl; by vertical walls 8 and 4, the outer wall having in it a hole 5 and the tw walls having at diagonal corners the perforated ears 6 and 7. These walls, with the hub, constitute a pocket for the reception of a can or vessel 8, closed on all sides, excepting as hereinafter specified, and this can or vessel is the lubri- A hole 9v is made in one side of the lubricant-receptacle to register with the hole 5, and said hole 9 is normally closed by a spring-pressed stopper 10, adapted to open linwardly for the introduction into the lubricant-receptacle yof suitable oil or other lubricant. Any number,

preferably two, tapering tubes l1 are fixed within the lubricant-receptacle and have openings 12 into them at the under side of their upper and wider ends, so as to fill with lubricant only as the receptacle rises in the turning of the wheel, and their lower ends open into ducts 13 in the hub or otherwise communicate with the axle 14. It will be observed that the upper sides of the upper ends of-the tubes are closed tight against the adjacent walls of the lubricant-receptacle, and hence no lubricant can enter these tubes from the outside, but the lubricant must enter the tubes from the under side and when these tubesare in position to admit it.

The lubricantreceptacle is held in the pocket by a diagonal bolt 15, fastened in the ears 6 and 7 and may be readily removed for renewals or repairs. 4

While the wheel is not inservice there is and can be no escape of lubricant, and the bearingor hub and axle will be lubricated only while the wheel is in slow motion either forward or backward, and hence enough lubricant will flow to the axle while the car is being moved for coupling to thoroughly oil the parts for the ordinary run from mine to tipple, or vice versa. It is necessary, however, that the wheel be turned suliiciently far-say one revolution-to enable the open ends or mouths 12 of the tubes to stand upward, and thus fill with oil, and when the receptacle reaches the highest point gravity and airpressure will suiiice to cause the oil to liow down to the axle. Should the wheel be run at too high speed, centrifugal action willA interrupt more or less the liow of the oil, and when the wheel is at rest so also is the oil and it cannot flow through the tubes.

Obviously the lubricant-receptacle may be filled whether it be for the time being above, below, or at the side of the axle.

1n using the term mine-car wheel we do not wish to be limited to acar-wheel for that one specific purpose, since obviously our invention is applicable to other car-wheels that require lubrication under conditions similar to the mine-car wheels, and our claims are to be read accordingly.

What we claim is- 1. A self-oiling wheel for mine-cars, comprising a pocket, a lubricant-receptacle arranged in said pocket, and tubes connecting the said lubricant-receptacle and the part to be lubricated, said tubes having inlet-openings on their under sides and adapted to collect and discharge lubricant only Whenthe- Wheel is running at a relatively low speed.

2. A self-oiling Wheel for mine-cars, comprisinga wheel, of substantially ordinary construction, having a pocket, a closed lubricantreceptacle arranged in said pocket and having a number of outlet-tubes closed on their upper sides and having openings on their under sides and discharging at their lower ends.

3. A self-oiling Wheel for mine-cars, comprisingawheel, of substantially ordinary construction` having a pocket, a closed lubricantreceptacle arranged in said pocket and having a number of tapering outlettubes,'the larger diameters of which are closed on their upper sides and open on their under sides, and discharging at their lower ends.

4. A self-oiling Wheel for mine-cars, comprisingk a pocket, a lubricant-receptacle arranged in said pocket, and tubes connecting the said lubricant-receptacle and the part to be lubricated, said tubes having inlet-openings on their under sides and adapted to collect and discharge lubricant only when the Wheel is running at arelatively low speed. and means to fasten the said lubricant-receptacle in said pocket.

5. A self-oiling Wheel for mine-ears, conlprising a pocket, a lubricant-receptacle arranged in said pocket, and tubes connecting the said lubricant-receptacle and the part to be lubricated, said tubes having inlet-openings onA their under sides and adapted to collect and discharge lubricant only when the Wheel is running at a relatively low speed, said pocket having diagonally-disposed ears, and a bolt secured inl said ears above the lubricant-receptacle.

6. A self-oiling wheel for mine-cars, coinprising a pocket, a lubricant-receptacle arranged in said pocket, and tubes connecting the said lubrieant-receptacle and the part to be lubricated, said tubes having inlet-openings on their under sides and adapted to eolleet and discharge lubricant only when the Wheel is running at a relatively low speed, and an automatic closure for the iilling-hole.

In testimony WhereoiI we have hereunto set our hands this 3d day of January, A. D. 1905.
